Pontiac Grand Prix: Problems & Solutions

edited March 20 in Pontiac
Hallo,I have been owner of Pontiac Grand Prix`98 for a year and half now and with 68000 km I haven`t had no problems till few months ago.Then I had problem taking out key from ignition.If I would wait couple of minutes I would hear "click sound" somewhere in driving wheel and not until then I would be able to take out the key.
Several mechanics took a look into this matter,but no one was smart enough to solve a problem.Last of them even changed ignition tumbler,module,electric release and did coding,but unfortunately for me and my CDN$400, I still have the same problem.If anyone knows how to deal with this,please let me know.

  • Hello all. I have had my 1995 grand prix for 3 years now and the wife just loves it. But we just had the transmission go out and have been trying to get some one to fix it for the past 4 months. they want $1800.00 to fix this trans, that is alot of money. We can not find a used trans any where. has any one else had this problem?
    the car will go forwards in 1st and 2nd but not in drive or Overdrive. I hope this does not happen to any of you, it's not fun.

    you should post in the existing thread "transmission traumas" to get an answer
  • I have a 1999 Grand Prix SE which is now taking on water during rainstorms. I previously had a 15 year old car with this problem, but this car is 4 years old! The water is leaking in on the front passenger side floor, coming down the slanted foot rest (whatever it's called). What could have happened? Is this easily fixable? Whatever the outcome, it's GOODBYE PONTIAC.
  • Do you happen to be using the AC during these rain storms? Do you get water in the floor with AC on and its not raining? A common problem for these vehicles is that the drain from the AC coil will get plugged causing the condensate from the coil to drain into the passenger side floor. Just something else you might want to check into.

  • Rob,

    No, I'm not running the AC and never had a problem when it was running. I read in the other GP forums that others have had this problem (other makes also)so it's not just me. Something about the evaporation unit???...
  • I own a 2000 Grand Prix and love it! I bought it brand new and it has never been in the shop, except for normal maintence
  • I took my 1999 GP SE to my mechanic - there was no clog in the drainage tubes, and hosing the car down did not produce another leak. All of the seals were intact. So how did the water get in? Does it take a specific kind of windy rainstorm? I'll have to wait for the next storm...

    For 4 years, not one ounce of trouble. But now I've had the injectors replaced 4 times in 6 months. Thank goodness for the extended warranty.

    I had the transmission go out in my '98 GTP around 2000. I don't remember the mileage but would guess it was under 30k.

    I understand it is or was a fairly common problem--something about the torque converter locking up prematurely which quickly fried the transmission. The dealership never told me what the problem was so I'm only assuming that's what it was. I noticed what felt like slight lugging under certain conditions and thought I'd mention it the next time I was in for service. A few days later I was by the side of the road.

    It was replaced (twice) under warranty, actually rebuilt the first time by the dealership and when that went out on the way home they just replaced it. They helped pay for the rental car, a very nice Volvo 850 GLT.

    Had exactly the same thing happen with my Bonneville. The rebuilt tranny died on the drive home from the dealership. Luckily, both times were under warranty. They too said it had something to do with the torque converter.

    My wife drives a 2001 GTP. She formerly had a 1998 GT. The GT, when low on fuel, would chime as well as the low fuel message coming on. The 2001 has never chimed, so when in for service recently, we asked that they fix that. After replacing a couple of parts (don't know what parts), they declared that a recent service bulletin said that any GP produced 1999 or later does not have the low fuel chime feature even though the owner's manual says it does. So we accepted that. Last night, however, we reached low fuel and the message came on and, guess what, it chimed. Hmmm. Anybody else have a 2000 or 2001 GP that chimes?
  • speedshiftspeedshift Posts: 1,598
    Interesting about the failure rate on rebuilt transmissions. At the time I had this feeling that all the mechanics drew straws and the one with the shortest straw had to rebuild the tranny. It took him over a week IIRC.

    But I loved that Volvo so I didn't mind too much.
  • I am the original owner of a 97 GTP which just turn 69K miles.

    Within the past year I have replace the alternator (failed), water pump (leaked) and installed its third battery.

    I also have a power steering problem with the power steering not being smooth or supplying the correct boost for the different speeds or amount of turn on the steering wheel. Have an appointment for repair.

    Maybe the car is jealous that I have been looking at new cars, but it seems to me to be a bit early it the car's life to have these failures.

    WRT to other problems in this discussion, no water getting into the people tank thru AC, seals or otherwise.
  • In the last 6 months i have replaced my alternator, water pump, lock tumbler, and my battery. i cant say that i am to happy with my GP. My new problem is this horrible whinning noise that i hear when i hit the gas. Im thinking transmission since once in a while the engine hesitates and i have to dip deeper into the throttle for the car to start moving faster. Anyone have these problems or know what they could be??

    I have a 97 Bonneville. 3.8 I had a similar progression, alternator, waterpump, and then the whining. It turned out to be the intake manifold which is problematic on the 3.8's. Unfortunately it caused my engine to seize. It's worth looking into if you have the 3.8, because it's kind of a silent killer. The whining kept getting chalked up to pulley noise every time we took the car in.

    Any details on how the intake manifold resulted in a seized engine? Coolant leak maybe?

    delcom - 5 years on a battery is normal

    alternator and water pump - I guessing you have about 75K miles or more on the GP - that is also normal

    Long story. Here's the condensed version. We knew the waterpump was going bad, and there was some loss of coolant, not a significant amount, and it wasn't external. Took it to the dealer because this was the second pump and it was a lifetime warranty. They fixed the pump and the squealing pulley. Said the plenum on the manifold was bad. There's a TSB out on this. Replaced the plenum and upper manifold. Drove it less than 100 miles and the engine seized. They're saying coolant leaked into Cylinder#4 and ruined the bearing. We're saying how did that happen when you fixed the manifold and we had no engine trouble previous to the fix? Now the car is sitting up there being autopsied and investigated by an independent investigator and we're waiting to see who gets to pay the $5400 for a new engine. GM is denying all responsibility for putting a plastic part in an area that is exposed to excessive heat, however have since replaced that part with a metal one as per the TSB. Currently there's a petition floating around with some 1000 signatures of people that have GM cars with this problem. I think it's Bonnevilles, Grand Prixs, Cavaliers and one of the Buick models that are involved.
  • Actually 50K on it, shesfyne after you got the manifold replaced did the whining stop and how much was did it cost?

    You know, it's tough to know what to attribute that whine to. At one point they tightened the serpentine belt, and it stopped, but shortly after that the engine went. Now they had tightened that belt before, and it stopped whining short term, but came back. Was it related, was it not even that belt? I don't know. I was just commenting on the similarity in the sequence of events. That and the fact that you have the 3.8 that is mentioned in the TSB. The manifold job, (upper plenum and upper intake) was $700. That seems to be the going rate give or take 100. I had 64K on mine. I looked at the petition and it seems to generally occur between 40K-70K.
  • What years are affected? I have just purchased a 2002 GP and would like to know if I need to have this done.

    Anyone have a good online reference for GP TSBs?
  • Got the power steering fixed. Dealer replaced the rack and pinion assembly. Cost $845. However---

    www.nhtsa.dot.gov has a recall posted on 11/6/02 for 97 Grand Prix's (on others) for rack and pinion problems. Notifications going out in Jan 03. Describes my problem exactly. Hard to turn left and over boost to the right. Have to wait until I get a recall letter to get reimbursed.

    For TSB info, go to www.alldata.com. It lists all the TSB's for each vehicle. Has TSB number, date and brief title. At least a start to tracking down a particular one.

    Here we go- one month in and 1,300 miles on the NEW 2003 GP GT- the car started to buck and lunge between 20/30 mph- yesterday afternoon- a little while later the SERVICE ENGINE SOON light came on.
    Anyone have anything similar, New or Older????

    I have an appointment first thing this Monday morning at the Pontiac dealership for repairs-fully covered but already a pain in the a**- for the time and inconvenience. - this should not happen with a NEW car. I'll post on what the
    problem was sometime this week.
    I hope this is not a pre-cursor of things to come with this car- I had the 2000 Bonneville SE for almost 3 years with only 2 problems- incorrect brake pads and a bad driver side window motor- never did the" Service Engine" light ever come on or did the car run rough !!!

    Chuck
  • I have a new 2k2 GT with 1400 miles on it and no problems so far. Perhaps you just were unlucky or a simple part failed. Hopefully this isn't any indication of the overall quality of your car.
  • fantascpfantascp Posts: 175
    Thanks for the info/support.- the problem is a faulty transmission- their not sure right now if its just a certain part or if the entire trans has to be replaced by GM. I got a loaner vehicle- a Jeep Liberty- at least for the next three or four days. When I find out exactly what is was in the trans i'll re-post.

    Chuck.
  • Anybody have any problems with the air flow control? I have the manual hvac sys and when I selct floor, it comes out thru the front vents. Also, had the problem with water on the passenger floor, dealer fixed it said it was water coming in thry a seal and the near the fan, which is almost behind the glovebox, almost $300 out of warranty (could also explain the blown fuses for the fan) I have 65K miles and only repl'd the water pump and alt., otherwise a very solid ride. Had the 3.2ltr dohc yamaha in a sho before this and the 3.8II blows it away.
  • My son's 1999 Grand Prix recently suffered a catastrophic engine failure. All he noticed was a slight loss of power before the engine seized. It would not crank and was towed to the nearest Pontiac dealer. This dealer did not have time to even look at the car and suggested we leave it with them for 2 weeks and they would try to get around to it(I'm serious). So we had to have it towed again to a nearby Chevy dealer. They looked at it that day and found the intake manifold had a hole in it and all cylinders were full of water. Engine was completely ruined and had to be replaced for a mere pitance of $5125. This is quite a boost to the bottom line at Pontiac. I contacted the 800 number for Pontiac and of course they basically told me to jump in the lake. I guess they knew they already had my money so why care? Let me add another 2 cents of mine I would not have another Pontiac if you gave it to me(I'm serious).
    This car was well cared for and had 57k miles when it bit the dust.
    Anyone know anything about the petition that is going around about this problem with the 3800 series engine? Maybe if enough people get together on this issue Pontiac will decide to actually care about their customers while they still have some left.

    but I would go straight to small claims court


    good luck

    It's easy....just trade it in for a better car! I had nothing but trouble with my GP, steering racks, sunroof leak and squeek, trunk leaks. So many other people had the same issues...so not just my car. Had to sue GM to buy it back. It was well worth it. My new car is not perfect, but a 1000 times better that the GP. I miss its styling but not its lack of durability.
  • I have a 2001 GP SE with 38k miles. I purchased the car used and have been hearing excessive valve noise on cold starts ever since I have owned the car. I took it in to the dealer while it was still under warranty to check out the problem. The dealer stated that there was a Pontiac technical service bulletin that stated that there would be valve noise with these cars on start up and it would go away as the engine warmed, so there was no problem.

    My SES light just came on so I am going to have to take it to find out if there is a problem. Before I take it in for service, I was wondering if anyone found the valve noise to be a problem that should be repaired.
  • I have a similar problem with my 98. It only has
    15K miles on it(really), and am not able to shift
    into gear or pull the key out after it is shut off. Dealer says its the solenoid by the gear shift lever. Price $345. Dealer asked if anything was spilled in it, and the answer is no.
    The car looks new inside and out. Anyone if GM
    will warranty something like this?
